Abstract: 1,198,237. Airing and securing bed clothes. D. H. LECAT. 20 June, 1969 [21 June, 1968; 31 Dec., 1968], No. 31231/69. Heading A4J. A rigid frame 7 carries bed-clothes 4-6 and is pivoted at 10 for lifting to the airing position shown. The side members of the frame are telescopic and are lengthened automatically when the frame is moved into the position shown to tension the sheets. Further side members 17 secure the sides of the bed clothes when the frame is lowered and a similar device secures the foot. A dust box 16 is provided and in an embodiment (Fig. 6) the bed frame slides horizontally on supports (50) away from a wall as the frame 7 is elevated, thus allowing the headboard (55) of the bed to lie adjacent the wall when the bed is made, but allowing dust to fall into a box when the clothes are elevated and shaken.

Title: Improvements in or relating to semi-conductor devices
IPC: H01L23/31
Filed: 1959-09-14
Abstract: 938,051. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 14, 1959 [Sept. 16, 1958], No. 31232/59. Drawings to Specification. Class 37. In a semi-conductor device the semi-conductor surface is provided with at least a mono-layer coating of an organic substance having at least one polar group and at least one non-polar group, the polar groups in the monolayer being adsorbed on said semiconductor surface and the non-polar groups being directed outwardly to provide a waterrepellant surface, the semi-conductor body provided with said coating being hermetically sealed within an envelope. There are two particular examples. In one an alloyed germanium PNP transistor after cleaning is dipcoated in " Desicote " (Trade Mark), and then sealed in a vacuum-tight glass envelope partly filled with previously dried silicone grease. In the other an alloyed germanium PNP transistor is sealed in a glass envelope approximately 60% filled with a previously dried mixture of silicone grease with 3% stearic acid, and is heated to 140‹ C. for 6 hours to form at least a mono-layer of stearic acid on the germanium body. Elsewhere in the description the use of very many varied organic compounds is disclosed and it is stated that the devices may also be made from silicon or other semiconductors such as the A<SP>III</SP> B<SP>V</SP> compounds, including, gallium arsenide and indium phosphide. The envelopes of the devices may be filled with conventional filling gases such as nitrogen, hydrogen, rare gases or mixtures thereof, or may be filled with air. Processes for applying the organic compound to the semiconductor body include application from the vapour state, dipping in the liquid compound, dipping in solutions of the compound, and by diffusion, preferably with the aid of a heating step during fabrication, from a store of the material provided within the sealed envelope. With the latter process, applicable mainly to the higher fatty acids, the store of organic material may be a mixture of the material with silicone grease as in the second example above, or it may be a store of the material separated from the semi-conductor body within the envelope by a porous well, e.g. of quartz wool or asbestos or by a pervious lacquer layer on the body. Reference, has been directed by the Comptroller to Specification 827,068.

Abstract: 208,624. Dyson, J. W., and Garside, E. Nov. 16, 1922. Starting and stopping arrangements; brake mechanism.-To ensure that the loom shall stop with the shuttle in the box, an adjustable catch A, Fig. 3, which is pivoted on a part a on the lay B and normally rests on a cranked finger a<5>, is adapted to be raised into the path of a lever a<2> having an arm a<4> which engages a finger c on the shaft C of the starting handle C<1> and thereby stops the loom. The cranked finger a<5> is pivoted on a spring-controlled lever connected by a cord a<9>, Fig. 2, to an adjustable rocking piece a<11> to which are attached cords a<13> accessible to the operative from the front, back, and each side of the loom. When one of the cords a<13> is pulled, the finger a<5> is raised and a pin c<1> on an arm c of the starting-handle engages a T-slot in a lever c<3> to move a rod c<5> carrying the beltfork. At the same time a brake-band c<15> around the fast pulley E is tightened by a flexible member c<9> secured to the band and to the rod c<5>. The lever c<3> may be connected to a clutchoperating device in looms not provided with fast and loose pulleys. In cases where the shaft C of the starting handle C<1> is dispensed with, the lever a<2> carries a part adapted to engage the lower part of the handle.

Title: A direct-current to direct-current converter or a direct voltage to direct voltage convertor
IPC: G01R15/20
Filed: 1968-07-01
Abstract: 1,189,410. Semi-conductor amplifier. SIEMENS A.G. 1 July, 1968 [1 July, 1967], No. 31347/68. Heading H3T. [Also in Division G1] A D.C. to D.C. converter (amplifier) has a single magnetic circuit 3, 4 including two air gaps containing respective magneto-resistive elements 1, 2 which are connected with two other impedances (not shown) in a bridge whose output is amplified and is proportional to the current supplied to an input winding 8, the flux from which is opposed by that produced in a feedback winding 7 by current from the amplifier output; the gaps being premagnetized as by magnets 5a, 5b. The magnets may be permanent or electromagnets. The windings 7, 8 are carried on respective core parts 3, 4 which are U-shaped in Fig. 1; or one (3, Fig. 2, not shown) may be formed as a straight bar carrying a single permanent magnet (5) for premagnetization. In this case a single coil (10) carries the input current, and two coils (11) constitute the feedback winding. The straight core member (3) may be made thin (Figs. 3, 5, not shown) so that it saturates to limit the flux through the elements 1, 2 if the input current accidentally exceeds the maximum value of the current in the feedback coil (11), this being limited by the amplifier. The crosssection of the core parts 3, 4 may be reduced (Figs. 5, 6, not shown), and shield plates (12), which may have a lower magnetic grade than the core parts and preferably have a high saturation flux density, are provided to intercept stray flux (Fig. 7, not shown) which could cause premature saturation of the core member (3). The saturable core member (3) may be placed in the same plane as, and between, the core part (4, Fig. 8, not shown) and the plate (12). A constructional arrangement is described for the core (Fig. 9, not shown), and includes, as well as some of the above features, heat conductive, resilient members (25-28) separating core parts and plates. These members may be of copper, one (28) carrying the magnets (5a, 5b); and brass members (30) carry the magneto resistive elements (1, 2). The core is laminated or of tape. Temperature compensation includes making the windings of the same temperature coefficient material; and in the case where the feedback winding is in series with a resistance across which an output voltage is taken, this resistance has the same temperature coefficient.
